Control tests test I

Decide whether these statements are true or false:

1. a). Floating and troweling is a process of roughening the surface.

b). Floating and troweling is a process of curing the surface.

c). Floating and troweling is a process of compacting and smoothing the surface.

2. a). Once concrete has been placed and consolidated it must be compacted.

b). Once concrete has been placed and consolidated it must be allowed to cure properly.

c). Once concrete has been placed and consolidated it must be mechanically finished.

3. a). As the concrete hardens and gains strength it becomes less vulnerable.

b). As the concrete hardens and gains strength, this will generate internal stresses.

c). As the concrete hardens and gains strength, pools of water should be allowed to form on the surface.

4. a). Cold weather causes the concrete to evaporate rapidly.

b). Cold weather causes the concrete being destroyed beyond repair.

c). Cold weather causes the concrete to harden much more slowly than hot weather.

5. a). Proper curing of concrete generally comes down to two factors, evaporation and smoothing.

b). Proper curing of concrete generally comes down to two factors, keeping it moist and keeping it supported.

c). Proper curing of concrete generally comes down to two factors, holding to dimensional tolerances and avoiding cracking.
